Terrible Connection Issues
Not always recognized as being plugged in, when it does, randomly will disconnect, turn off tv and connection is lost, sound lags behind video and changing that option completely disconnects the sound bar and won’t recognize. Returning the product to Best Buy.

Great Sound, horrible connection problems!!!
Buyer Beware! This soundbar for $150 is amazing in sound quality. The sub is great and the bar fills the room with sound. However I’ve had nothing but connection issues. No matter what the sound bar does not sync perfectly with the tv. It’s always half a second off making it look like I’m watching something dubbed all the time. Only with the cable box does this happen. The PS4 syncs just fine. I also had to dig and do a bunch of research just to hook it up. The instructions were horrible and the remote is useless.

Can’t control soundbar with my tv remotes although I could yesterday. Instructions suggest I can but they don’t elaborate. Subwoofer is so much weaker than in BestBuy I wondered if it was on. Instructions say I can use HDMI ARC cable, but I still must connect the Optical cable.
Returning tomorrow

Great Set
The speakers were very easy to connect with my TV and work as expected. The wireless subwoofer was already paired with the soundbar and works great, I love the extra thump. Overall a good value with very good performance.

Sound is great
Only thing I don't like is it will not power on with direct tv remote. If anyone has figured this out let me no.

Outstanding sound
This sound bar was bought to use with a Roku flat screen TV in our backyard. TV is not mounted and is moved depending on where we sit.
Price was important since it is used outside. Picked it up from Best Buy for $149. Watching football outside today and sound is loud and clear. Also bass is good for outside.
Very happy with choice and I will recommend this system to friends who do the same outback.

S2. Works occasionally
Its just OK when it works, woofer is too quiet. S2 turns off (usually by itself it may not turn on. It's been off for hours, and I am losing faith that it decide to work again. I will return to store for refund.

A shopper on Dec 15, 2018
  Only one is required. HDMI ARC is preferred if your TV has a compatible input.
